Facial electromyography (fEMG) refers to an electromyography (EMG) technique that measures muscle activity by detecting and amplifying the tiny electrical impulses that are generated by muscle fibers when they contract.

Can an EMG be done on the face?

EMG. Electromyography is a neuroelectrophysiological test that evaluates the health and integrity of the facial nerve.

What nerve Innervates the corrugator?

The angular nerve supplies branches to the corrugator supercilii and procerus muscles. The corrugator thus receives innervation not only from the frontal branch, which runs above the eye, but also from the angular nerve, which runs below.

What EMG can diagnose?

An EMG can be used to diagnose a wide variety of neuromuscular diseases, motor problems, nerve injuries, or degenerative conditions, such as:

What is a corrugator operator?

What is a paper corrugator?

A corrugator is a set of machines designed to bring together three, five or seven sheets of paper to form single, double or triple wall board in a continuous process. The 3 key stages: Corrugating the flutes and gluing to a single liner. Gluing the outside liner to make a rigid board.
